Helpfully LOCOG only puts the start time on the official website. Yeah, thanks for that. Not like anyone needs to know, is it.

A bit of digging reveals the race is due to end a little after 4pm. Getting to a TV somewhere around 3pm should give you the last lap or two of the Box Hill circuit plus the fast run-in to Central London, I reckon.

Be warned, however - I went to get a round of drinks at my sister's wedding and spent a couple of minutes, no more, watching what was happening in the FA Cup Final on the TV by the bar.

Family legend now has it set in stone that I actually disappeared from the wedding to watch the whole match...

We're going down, and the estimated times for the race to pass through given sections are:

Location/time

The Mall - START 10am

Hampton Court Palace - 10.35am

Walton-on-Thames - 10.45am

Ripley Village - 11.05am

Gomshall - 11.25am

Westcott - 11.30am

Dorking - 11.35am

Box Hill - circuit entrance 11.40am

Box Hill - circuit exit 2.50pm

Esher - 3.05pm

Hampton Court Palace - 3.10pm

Kingston Upon Thames - 3.15pm

Richmond Park - 3.20pm

Putney Bridge - 3.30pm

Fulham - 3.35pm

The Mall - FINISH 3.40pm

So taking into account Simon's warning, I reckon if you set things up with a couple of 'got a dodgy stomach, love' lines, then nip 'off to the loo' by 3:20, you'll have until about 4 before someone comes looking for you!

Book a hotel room at the venue (assuming you can) and just head off 'for a lie down' for an hour, the time between 3 and 5 is usually a dead spot at weddings anyway unless the couple have got some 'interesting' timings for food/speeches etc.

In fact, most hotel's only let you check in at around 3 so it's the perfect time to get into your room and 'unpack'.
